Hydrogeochemical effects of injecting wastes into a limestone aquifer near Pensacola, Florida
Donald A. Goolsby
1971, Groundwater (9) 13-19
Acidic industrial wastes have been injected into deep wells in a limestone aquifer near Pensacola, Florida, since 1963. Prior geohydrologic studies in the area had indicated that the limestone aquifer contained nonpotable water and was overlain by an extensive clay confining layer.Two injection wells are presently being used to inject...
Scanning electron microscopy of clays and clay minerals
B.F. Bohor, R.E. Hughes
1971, Clays and Clay Minerals (19) 49-54
The scanning electron microscope (SEM) proves to be ideally suited for studying the configuration, texture, and fabric of clay samples. Growth mechanics of crystalline units—interpenetration and interlocking of crystallites, crystal habits, twinning, helical growth, and topotaxis—also are uniquely revealed by the SEM.Authigenic kaolins make up the bulk of the examples...
A general evaluation of the frequency distribution of clay and associated minerals in the alluvial soils of Ceylon
J.W. Herath, R.W. Grimshaw
1971, Geoderma (5) 119-130
Clay mineral analyses were made of several alluvial clay materials from Ceylon. These studies show that the soil materials can be divided into 3 clay mineral provinces on the basis of the frequency distribution of...
Na+, K+-activated-ATPase inhibition in rainbow trout: A site for organochlorine pesticide toxicity?
Paul W. Davis, Gary A. Wedemeyer
1971, Comparative Biochemistry and Physiology, Part B: Comparative Biochemistry (40) 823-827
1. The Na+, K+-activated, Mg2+-dependent-ATPase enzyme system in a heavy microsomal fraction of rainbow trout (Salmo gairdneri) brain was inhibited in vitro by chlorinated hydrocarbon pesticides.2. T50 (concentration at 50 per cent inhibition) values for dicofol, endosulfan and DDT were <span class="formulatext stixSupport mathImg" title="Click to view...

A decade of international cooperation brings a standard seismic point of view
H. S Whitcomb Jr.
1971, Earthquake Information Bulletin (USGS) (3) 16-19
Whether in a castle in Italy, a police station in Iceland, o an abandoned gold mine in Australia, the sensitive instruments in the Worldwide Seismograph Network send a steady flow of standard earthquake records to the geophysical scientific community. They provide the raw data that make possible very precise earthquake...
Thermoluminescence of Apollo 12 lunar samples
Richard R. Doell, G. Brent Dalrymple
1971, Earth and Planetary Science Letters (10) 357-360
Thermoluminescence (TL) glow curve and decay characteristics of Apollo 12 fines and soil samples are similar to those from Apollo 11. Interpretation of the results from the core sample is difficult because of inadequate sample, spacing, but it appears that the part...

Population biology of lake trout (Salvelinus namaycush) of Lake Superior before 1950
Gary T. Sakagawa, Richard L. Pycha
1971, Journal of the Fisheries Research Board of Canada (28) 65-71
Scale samples collected in 1948 were used to estimate the instantaneous total mortality rate (0.70) and growth for lake trout (Salvelinus namaycush) in Lake Superior before the population had been significantly reduced by the sea lamprey (Petromyzon marinus). Indirect evidence indicates that the instantaneous natural mortality rate was probably 0.10–0.25....
Effects of temperature on electrolyte balance and osmoregulation of the alewife (Alosa pseudoharengus) in fresh and sea water
Jon G. Stanley, Peter J. Colby
1971, Transactions of the American Fisheries Society (100) 624-638
A study of the effects of temperature and salinity on ionoregulation in the alewife, Alosa pseudoharengus, revealed that concentrations of sodium, potassium, and calcium in plasma and muscle were similar in fish adapted to fresh water and those adapted to sea water. The non-stressed alewife is apparently an excellent...

Albinism in lampreys in the upper Great Lakes
Robert A. Braem, Everett L. King

Albinism in fishes is relatively rare except in some stocks of hatchery-reared salmonids. In the Petromyzonidae, only four albino lampreys have been reported....
Selective food preferences of walleyes of the 1959 year class in Lake Erie
John W. Parsons
1971, Transactions of the American Fisheries Society (100) 474-485
Stomachs were examined from 1,473 walleyes (Stizostedion vitreum vitreum) of the 1959 year class collected in western Lake Erie from June 1959 to October 1960. In the same period, the relative abundance and lengths of potential forage species were determined from trawl catches. The walleye fed almost entirely on fish....
Giant American brook lampreys, Lampetra lamottei, in the upper Great Lakes
Patrick J. Manion, Harold A. Purvis
1971, Journal of the Fisheries Research Board of Canada (28) 616-620
Five female American brook lampreys, Lampetra lamottei, collected in lakes Michigan and Huron averaged nearly twice as long and about six times as heavy as American brook lampreys of normal size. Three factors suggested that the giant lampreys may have fed parasitically after metamorphosis: morphological adaptations of the species for parasitic...
A procedure for testing the antigenicity of vaccines for immunization of fish against Furunculosis
Jamieson E. Holway, G.W. Klontz
1971, Progressive Fish-Culturist 42-44
Furnunculosis, a bacterial disease caused by Aeromonas salmonicida, is potentially one of the most devastating diseases in trout and salmon hatcheries. The disease may be controlled by three methods. The most frequently used method of control has been drug therapy. Unfortunately, the bacteria often develop resistance to the...
Some blood chemistry values for the juvenile coho salmon (Oncorhynchus kisutch)
Gary Wedemeyer, K. Chatterton
1971, Journal of the Fisheries Research Board of Canada 606-608
Overlapping Gaussian distribution curves were resolved into normal ranges for 1800 clinical test values obtained from caudal arterial blood or plasma of more than 1000 juvenile coho salmon (Oncorhynchus kisutch) held under defined conditions of diet and temperature. Estimated normal blood chemistry ranges were bicarbonate, 9.5–12.6 mEq/liter; blood urea nitrogen (BUN),...

Spectral reflectance and photometric properties of selected rocks
Robert D. Watson
1971, Remote Sensing of Environment (2) 95-100
Studies of the spectral reflectance and photometric properties of selected rocks at the USGS Mill Creek, Oklahoma, remote sensing test site demonstrate that discrimination of rock types is possible through reflection measurements, but that the discrimination is complicated by surface conditions, such as weathering and lichen growth. Comparisons between fresh-broken,...
Kaersutite - A product of reaction between pargasite and basanite at Dish Hill, California
H. G. Wilshire, L. C. Calk, E.C. Schwarzman
1971, Earth and Planetary Science Letters (10) 281-284
Paragasitic amphibole, occurring interstitially and as veins in peridotite inclusions in basanite, has reacted with the host basanite to form kaersutitic amphibole. The amphibole compositions vary with respect to distance from the edge of the xenolith; iron, titanium, and potassium contents are...
Geomagnetic polarity epochs: age and duration of the olduvai normal polarity event
C. S. Grommé, R. L. Hay

New data show that the Olduvai normal geomagnetic polarity event is represented in Olduvai Gorge, Tanzania, by rocks covering a time span of roughly from 0.1 to 0.2 my and is no older than 2.0 my. Hence the long normal polarity event...
Sea level as affected by river runoff, Eastern United States

Variations in annual river inflow account for 7 to 21 percent of the total variation in average annual sea level along the Atlantic and Gulf of Mexico coasts of the United States. This compares with 29 to 68 percent of the total variation that can be attributed to the secular...
